The superficial degree of divergences will be denoted \(\omega (G)\) 
(sometimes it is also called the index of divergence) and \(d(G)\)  is
the number of partial derivatives of the external lines of the field
\(h_{\mu \nu }\)  in the diagram. Taking into account the powers of
momenta in all elements of the diagrams (see, e.g., [1]} for
a detailed general treatment), the general expression is
\(\omega (G)+d(G)\,=\, \sum \limits _{l_{int}}(4 - r_I)\,-\,4V \,+\,4\, + \,\sum \limits _{V}K_V,\)
